[Mitoguazone (methylglyoxal bis(guanylhydrazone))--its status and prospects]
Arch Geschwulstforsch 1989;59(2):135-48.PMID:2655552doi
Because of its severe side effects, initial clinical trials of the antineoplastic compound Mitoguazone (Methyl-GAG, M-G) were ceased in the middle of 1960s. One decade later pharmacokinetically guided dose schedules as well as new experimental data on the antiproliferative mechanism of action stimulated new clinical studies. First results indicated that M-G had single-agent activity against various tumors such as acute leukemia and malignant lymphoma connected with acceptable tolerance. M-G seems to be effective especially in combination with other antineoplastic drugs. Its final evaluation may be reserved to further randomized trials. Recently, the psoriasis vulgaris is expected to be an additional field of the application of M-G. In this minireview data on synthesis, preclinical pharmacology, pharmacokinetics, biochemical effects and toxicology of M-G are given. Furthermore, clinical findings on M-G concerning its pharmacokinetic behaviour, antitumor and antipsoriatic activities are described.
Mitoguazone induces apoptosis via a p53-independent mechanism
Anticancer Drugs 1998 Aug;9(7):635-40.PMID:9773808DOI:10.1097/00001813-199808000-00009.
Mitoguazone (methylglyoxal bisguanylhydrazone, methyl-GAG or MGBG) is a synthetic polycarbonyl derivative with activity in patients with Hodgkin's and non-Hodgkin's lymphoma, head and neck cancer, prostate cancer, and esophageal cancer. Mitoguazone has also recently been documented to have activity in patients with AIDS-related lymphoma. Among anticancer drugs, Mitoguazone has a unique mechanism of action via interference with the polyamine biosynthetic pathway. Polyamines stabilize DNA structure by non-covalent cross-bridging between phosphate groups on opposite strands. In addition, Mitoguazone causes uncoupling of oxidative phosphorylation. In this study, the ability of Mitoguazone to induce apoptosis by inhibiting the polyamine pathway was assessed in three Burkitt's lymphoma cell lines (Raji, Ramos and Daudi) and one prostate carcinoma cell line (MPC 3). Additional evaluations were performed in two human breast cancer cell lines (MCF7 with wild-type p53 and VM4K with mutated p53) to determine whether the p53 tumor suppressor gene was required for efficient apoptosis induction. The present study demonstrated that Mitoguazone induces apoptosis in all the different human cancer cell lines tested in a concentration- and time-dependent way, and triggers a p53-independent programmed cell death in the human breast cancer MCF7 cell line.
Pharmacokinetic profile of Mitoguazone (MGBG) in patients with AIDS related non-Hodgkin's lymphoma
Invest New Drugs 1996;14(2):227-34.PMID:8913846DOI:10.1007/BF00210796.
Mitoguazone is a unique chemotherapeutic agent whose activity is believed to result primarily from the competitive inhibition of S-adenosyl-methionine decarboxylase leading to a disruption in polyamine biosynthesis. Initial clinical trials demonstrated that the dose-limiting toxicities (mucositis and myelosuppression) of Mitoguazone were both dose and schedule dependent. Early pharmacokinetic studies of Mitoguazone in man revealed a prolonged half-life. Concurrent with a recent Phase II trial of Mitoguazone in patients with AIDS related non-Hodgkin's lymphoma, the single dose pharmacokinetics of Mitoguazone were characterized. Twelve patients received 600 mg/m2 of intravenous Mitoguazone over 30 minutes on an intermittent every 2 week schedule. Blood, urine, cerebrospinal fluid (CSF), pleural fluid and tissue samples were collected and analyzed by HPLC. Mitoguazone was cleared from the plasma triexponentially with a harmonic mean terminal half-life of 175 hours and a mean residence time of 192 hours. Peak plasma levels occurred immediately post-infusion, ranged from 6.47 to 42.8 micrograms/ml, and remained (for an extended period) well above the reported concentration for inhibition of polyamine biosynthesis. Plasma clearance averaged 4.73 l/hr/m2 with a relatively large apparent volume of distribution at steady-state of 1012 l/m2 indicating tissue sequestration. Renal excretion of unchanged Mitoguazone accounted for an average of 15.8% of the dose within 48 to 72 hours post-administration. Detectable levels of drug were present in random voided samples eight days post-dose. Mitoguazone levels in CSF ranged from 22 to 186 ng/ml post-dose with CSF/plasma ratios ranging from 0.6% to 7%. The pleural fluid/plasma ratio was approximately 1. Tissue levels of Mitoguazone were highest in the liver followed by lymph node, spleen and the brain.
Mitoguazone therapy in patients with refractory or relapsed AIDS-related lymphoma: results from a multicenter phase II trial
J Clin Oncol 1997 Mar;15(3):1094-103.PMID:9060550DOI:10.1200/JCO.1997.15.3.1094.
Purpose: Patients with AIDS-related lymphoma usually have extensive lymphomatous disease, with relatively frequent involvement of the CNS. Approximately half may achieve complete remission after chemotherapy. Mitoguazone, an inhibitor of polyamine biosynthesis, has demonstrated efficacy in patients with de novo recurrent lymphoma. The drug is relatively nonmyelotoxic and may cross the blood-brain barrier. The current study was designed to assess the safety and potential efficacy of Mitoguazone in patients with relapsed or refractory AIDS-lymphoma. Patients and methods: Thirty-five patients were accrued, all of whom had failed one (51%) or multiple (two to six) prior regimens. Mitoguazone (600 mg/m2) was given intravenously on days 1 and 8, and then every 2 weeks, until best response, progression, or toxicity. Results: The median age was 39 years. High-grade lymphoma was diagnosed in 29 patients (83%). Extranodal disease was present in 30 patients (86%), with multiple extranodal sites (two to seven) in 18 (51%). The median CD4 cell count at study entry was 66/dL (range, zero to 549). Twenty-six patients were assessable for response. The objective response rate was 23% (95% confidence interval [CI], 6.9 to 39.3), with complete remission in three patients (11.5%), and partial remission (PR) in three patients (11.5%). Six patients experienced stable disease. Median survival from study entry was 2.6 months for the group as a whole; 21.5 months (range, 3.8 to 29.1) in complete responders, 5.6 months (range, 3.8 to 34.8) in partial responders. The most common toxicities occurred solely during drug infusion and included vasodilation (63%), paresthesia (86%), and somnolence (17%). Fourteen patients (40%) experienced nausea and 16 (46%) vomiting (grade 3 in one). Ten patients (29%) developed stomatitis, including grade 3 in two and grade 4 in one. Seven patients (20%) developed neutropenia, with grade 4 in one. Thrombocytopenia occurred in nine patients (26%). While on study, three patients developed sepsis, four had pneumonia, and two developed opportunistic infections. Conclusion: Mitoguazone is an effective agent in patients with multiply relapsed or refractory AIDS-related lymphoma, with acceptable toxicity. Further study in patients with newly diagnosed disease is warranted.
A phase I human trial of Mitoguazone and gemcitabine sequential bi-weekly treatment of cancer patients
Cancer Invest 2003;21(4):542-9.PMID:14533444DOI:10.1081/cnv-120022370.
Our previous studies have demonstrated the existence of synergism in a combination therapy using Mitoguazone and gemcitabine when the Mitoguazone is administered 24 hours before gemcitabine. Based on the cell culture and animal experimental results, a phase I clinical trial was performed in order to determine the toxicity of the combined treatment. Mitoguazone and gemcitabine were administered sequentially: Mitoguazone on day 1 and gemcitabine on day 2. This cycle was repeated every 2 weeks. The dosages of these two drugs were varied between patients. Ten patients were enrolled in the study. Six patients began treatment at dose level 1 (Mitoguazone 500 mg/m2, gemcitabine 1500 mg/m2), three at dose level 2 (Mitoguazone 500 mg/m2, gemcitabine 2000 mg/m2), and one at dose level 3 (Mitoguazone 600 mg/m2, gemcitabine 2000 mg/m2). Dose-limiting toxicity (DLT) was only observed in two patients treated at dose level 1 and one patient treated at dose level 3, while all the other patients only experienced nonhematologic toxicity, such as asthenia and mucositis. Two melanoma patients showed responses (one partial and one minor) to the treatment. One lymphoma patient also showed a brief partial response. This phase I trial indicated that the combination of Mitoguazone and gemcitabine had limited but noticeable activity for treatment of cancer patients. Further study on the toxicity and on the effect of the scheduled mitoguazone-gemcitabine combination is needed.
